In inteli: Interval Estimation by Likelihood Method

Testing Function for Variance Ratio of Two Samples from Normal Distribution

Description

Testing function for variance ratio of two samples assuming normal distribution by LI method. O2 type likelihood function plot is also shown. Smaller sample is allocated to be in the nominator for more accurate and precise estimation.

Arguments

set.a	a numeric vector of data values; mandatory, pre-allocation
set.b	a numeric vector of data values; mandatory, pre-allocation
conf.level	confidence level for the interval estimation
df	degree of freedom for likelihood interval; default is 2.4
k	cutoff value for likelihood interval. If not specified, F-test is used.

Value

demo	basic demographics of data
interval	estimated interval by LI and CI.
stat	statistical values, such as p-value and likelihood ratio
verdict	estimation result as a sentence
plot	log likelihood function plot (O2 type)

Examples

  x <- rnorm(30, 0, 1)
  y <- rnorm(20, 0, 1)
  qliv(x, y) # x placed in the denominator
